What does this agent do, and when should you use it?
This repository provides a set of Markdown-based 'skills' for AI coding agents to perform marketing tasks such as conversion optimization, copywriting, SEO, analytics, and growth engineering. It follows the Agent Skills specification, making it compatible with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent supporting the spec. The core is the 'product-marketing' skill, which holds product context and is read by all other skills first. There are over 50 skills, including cro, copywriting, seo-audit, analytics, emails, and ads. Installation is flexible via the npx skills CLI, Claude Code plugin, or manual copying. The repository is maintained by Corey Haines, a conversion optimization specialist.
It provides a set of skills that AI agents can invoke. Each skill is a Markdown file with specialized knowledge and workflows for a specific task. Agents call these skills when handling marketing requests, such as optimizing landing pages (cro), writing copy (copywriting), performing SEO audits (seo-audit), setting up analytics (analytics), creating email sequences (emails), and more. Skills reference each other and build on shared context from 'product-marketing'. After installation, users can trigger skills via natural language requests or direct commands like /cro. The repository itself doesn't execute code but provides instructions for agents.
- A SaaS founder wants to optimize conversion rate on a landing page, asking the agent to use the cro skill.
- A marketer needs homepage copy for their product, using the copywriting skill.
- A developer wants to set up GA4 event tracking, using the analytics skill.
- A B2B sales rep wants to create a cold email sequence, using the cold-email skill.
- A consultant needs a comprehensive marketing plan for a client, using the marketing-plan skill.
What are this agent's strengths and limitations?
- Comprehensive coverage across marketing domains: CRO, SEO, copy, analytics, sales enablement.
- Based on Agent Skills spec, compatible with multiple AI agents (Claude Code, Codex, Cursor, Windsurf).
- Skills are interconnected with a dependency map, enabling collaborative workflows (e.g., customer-research feeds copywriting and CRO).
- Multiple installation methods (CLI, plugin, manual) offer flexibility.
- Relies on the Agent Skills spec, so only works with agents that support it.
- Requires manual maintenance of the product-marketing context file for best results.
- Skills are Markdown instructions, not executable code, so effectiveness depends on the agent's interpretation.
- Some skills may become outdated; users need to update periodically.
